PP yog cov txheej txheem ua kom zoo, zoo heev crystalline thermoplastic cob muab tau los ntawm cov polymerization ntawm propylene. Raws li nws daim ntawv thov, nws muaj peev xwm raug faib ua PP txhaj tshuaj, PP yog nqus, PP fiber, PP zaj duab xis, thiab PP yeeb nkab. Ntawm cov plastics uas cov kheev siv hauv lub neej txhua hnub, polypropylene yog ib qho ntawm ntau yam sib txawv.
Kev ua tau zoo: 1. Kev ua haujlwm ntawm lub cev: tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis qab, thiab ruaj khov rau dej.
2. Kev ua cua sov: Nws muaj qhov ua haujlwm zoo hauv tshav kub, thiab nws cov khoom tuaj yeem raug sterilized ntawm qhov kub siab tshaj 100 ° C, thiab yuav tsis deformed ntawm 150 ° C nyob rau hauv qhov xwm txheej ntawm tsis muaj sab nraud quab yuam. Cov embrittlement kub yog -35 ℃, thiab qhov txias txias tsis zoo dua li polyethylene.
3. Tshuaj lom neeg ruaj khov: Qhov ruaj khov tshuaj zoo heev. Ntxiv nrog rau qhov corroded los ntawm cov ntsiab lus sulfuric acid thiab concentrated nitric acid, nws yog qhov ruaj khov rau ntau lwm yam tshuaj lom neeg. Polypropylene yog tsim rau ua cov kav dej sib txawv thiab fittings, thiab muaj kev txhim kho zoo corrosion.
4. Cov khoom hluav taws xob: Nws muaj lub zog ua kom qhov hluav taws xob ntau thiab tuaj yeem siv los ua cov hluav taws xob ua hluav taws xob tiv thaiv thaum kub kub tau nce. Nws qhov hluav taws xob tawg tseem ntau heev, haum rau siv raws li cov khoom siv hluav taws xob. Zoo tsis kam mus rau voltage thiab arc, tab sis hluav taws xob zoo li qub, yooj yim rau kev laus hauv kev sib cuag nrog tooj liab.
